BOTTLE.

SPECIFICATION forming part of Letters Patent No. 579,224, dated March 23, 189'?. Application filed October 20,1896. Serial No. 609,391. (No model.)

To all whom, t pray concern.'

Be it known that I, CHARLES E. FELCH, a citizen of the United States, residing at North Natick, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in bottles, the object of the same being to provide a bottle in which the cork or stopper thereof may be easily inserted and from which it may be easily removed when desired without the use of a corkscrew, but which cannot be accidentally removed from the pressure of gas within the bottle. i

A further object of the invention is to provide a bottle which cannot be opened without attracting attention, thereby avoiding the careless use of poison.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically pointed out in the appended claim.

Broadly stated, the invention consists of a bottle whose neck has a series of prismoidal wedge-shaped projections on its inner surface obliquely arranged substantially parallel one to the other and having the lower end of one located just beneath the lower end of the one next adjacent thereto.

In the drawings forming part of this speciiication, Figure l represents a perspective view of the neck of a bottle constructed according to my invention with the projections on the inner surface thereof shown in dotted lines. Fig. 2 is a vertical longitudinal section through the same. Fig. 3 is a cross-section on the line a: fr of Fig. 2, and Fig. 4L is a perspective view showing the cork or stopper applied.

Like reference-numerals indicate like parts in the different views.

The neck l of the bottle has formed upon its inner surface a series of parallel obliquelyarranged prismoidal projections 2 2, as clearly shown. These projections taper inwardljT from their upper ends, are substantially triangular in 'cross-section, and their lower ends form sharp projecting shoulders 3 3, the shoulder formed by each being located just above the shoulder formed by the one'next adjacent thereto. By this construction screw-threads are formed upon the inner surface of the neck l, which are adapted to be engaged by thecork or stopper 4.. The said cork is preferably made of some resilient material,which will yield when forced inwardly from the outer end of the neck l and will afterward expand at its lower end out around the shoulders 3 3 upon the lower ends of the projections 2. When thus in place, it is impossible for the said cork to be expelled by the internal pressure of gas, and it is also impossible for the cork to be removed without attracting attention. Securingwires for holding the cork in place are thereby dispensed with, and the careless use of poison contained in the bottle may be avoided. Furthermore, the said cork may, when desired, be removed without the use of a corkscrew by simply grasping said cork by its upper end and giving a slight upward and twisting pressure thereto, which will unscrew the same from the threads formed by the wedge-shaped prismoidal projections 2 2. Furthermore, by reason of the fact that the cork 4. cannot be accidentally removed, the use of the bottle for containing medicines and other compounds to be carried in a trunk, in a valise, or on the person is made safe and free from danger.

The device is extremely simple in construction, effective in operation, and can be produced at a cost but little if any in advance of the ordinary bottle now commonly used.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A bottle whose neck is provided with a series of parallel obliquely-arranged prismoidal projections upon the inner surface thereof,

the said projections being triangular in crosssection and whose lower ends form sharp abutting shoulders which are located respectively one above the other.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CHARLES n. Futon.
